Question

what is the ratio of the velocities of the two light waves travelling in vacuum and having wavelength 40000 angstrom and 80000 strom​

Answer 1

For light or any electromagnetic radiation,isa always the velocity is always meters

$c = 299792458$

per second, approximately 3

$3 \times {10}^{9}$

meters per second in vaccuum, and it is not dependent on the wavelength or frequency of the radiation. It only depends on the medium in which the rays travel.

the ratio will be 2:2

I hope this helpful answer

Answer 2

Answer:

The Velocity of light is constant

So, the answer is 1(one)
